Jackass penguins are efficient navigators. One oiled penguin which was rescued, cleaned and released on Robben Island in August 1971, travelled 800 km (around 500 miles) to Port Elizabeth within a month.

Jackass penguins are known as such because of the distinctive vocalization that they make- a bray very similar to a donkey's. However, they're technically now called African penguins. Presumably the switch was made due to the negative connotations of "jackass".
